A bitmap image only contains black and white pixels with no shades of gray and they also need to be at a high resolution. You get a bitmap image buy creating it by hand then scanning it in with a scanner. An example of this would be like if someone wrote their name in marker than uploaded it or created an image with a marker and uploading it would work too. Here's an example shown below.

Reverse is relatively easy to explain. Reverse is basically when you switch black and white colors on a page. An example is like you type a white font on a black background. This can be done in Photoshop, InDesign, and Illustrator.

Vector art is a pixel free graphic. It generates smooth lines when it's brought it because of like I said before it don't contain pixels. They are also not subjected to scaling restrictions. Not every vector format is the same though, which means they all can't be printed. This can be saved as an EPS or AI file. I didn't have anything to upload for this example.

Grayscale raster is basically a black and white image and is used many times in newspaper advertisements. This is done in Photoshop then you save it as an EPS file then bring it into InDesign. Example of a grayscale raster is below of my friend, who I took a picture of last semester.

Duotone raster is when an image is made up of two colors and one of the colors is usually black while the other is a spot color. It is a great way to add a visual interest to a job. This can be done in Photoshop and is usually saved as an EPS file. Example below is a duotone of a light blue and black. The reason its framed is because I had to move it into InDesign so I could put it on my blog.

A silhouette raster is when you erase the background behind your image usually by creating a mask or path that allows the subject to display without a background. It is also called a dropout. This can be done in Photoshop. It can also be created by the print service provider.

A full bleed raster is when an image covers the whole picture box in InDesign and goes to the bleed marks on the outsides, which is 0.125. It hits every side of the square to make sure the picture is in proportion and helps to make sure you know what will be cut off when it is printed. It's hard to show a picture of this one.

A four color raster is when an image or document uses only four colors in the project, which is CMYK (Cyan, Magenta, Yellow, and Black.) Most files that are printed are in CMYK just a quick note to this as well. This one is basically all ready set up for you in an InDesign document so its not too complicated to figure out.

Screen tint is when you want to fade or give your object more shade in a document to make it have a neat feature to your project. I used the book, Print Production with Adobe Creative Suite Applications by Claudi McCue to answer these questions for this blog. All images were taken or created by me.
